Given numbers are 390,442,753,706,802
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 390,442,753,706,802 is 235562593890.
Find LCM of 390,442,753,706,802 with Prime Factorization
| 2 | 390, 442, 753, 706, 802 |
| 3 | 195, 221, 753, 353, 401 |
| 13 | 65, 221, 251, 353, 401 |
| 5, 17, 251, 353, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 5 x 17 x 251 x 353 x 401 = 235562593890
Therefore, the lowest common multiple of 390,442,753,706,802 is 235562593890.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
390 x 442 x 753 x 706 x 802 = 73495529293680
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
442 : 1, 2, 13, 17, 26, 34, 221, 442
753 : 1, 3, 251, 753
706 : 1, 2, 353, 706
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,442,753,706,802, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
442:2x 13x 17
753:3x 251
706:2x 353
802:2x 401
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 13 = 312
Therefore, the value for common factors is 312.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 73495529293680/(1x312)
LCM = 73495529293680/312
LCM = 235562593890
Thus, we can understand that the LCM of 390,442,753,706,802 is 235562593890.
